摘要:

采用随机区组试验设计,通过方差分析、多重比较及回归分析,研究不同配方基质性质与油松容器苗生长及生理特性的关系和对苗木生长的影响。结果表明:不同基质对油松容器苗的地径、高径比、单株鲜质量、地下干质量影响存在显著性差异,对苗木单株干质量、地上干质量、地上鲜质量的影响差异达极显著水平;不同基质的苗木在顶芽干质量、根系活力和体内碳水化合物含量上也存在明显差异;基质的密度、全磷和速效磷的含量是影响油松容器苗生长的主要因子;基质中碱解氮的含量是影响容器苗地上与地下部分比例关系的主要因子;在北方培育油松容器苗,基质配方以表土40%、黄色粘土15%、松林表土20%、腐熟粪肥20、炉灰渣5%的配方比例,质地为中壤土,密度10t·m-3,全磷含量达0.8g·kg-1,速效磷含量90mg·kg-1,速效钾含量260mg·kg-1,碱解氮含量112mg·kg-1,有机质含量34g·kg-1的微酸性土(pH=6.3)为佳。

Abstract:

Using randomized block experiment design and variance analysis, multiple comparisons and regression analysis methods; the effects of the container-growing seedling were systematically analyzed. The results showed that the basal diameter, H/D, total fresh mass and under ground dry mass of container seedling presence significant difference; the difference of dry mass, under ground mass and aboveground fresh mass attained best significant level; the dry mass of phyllogen, activity of root system and soluble sugar content also presence significant difference. The volume mass of the medium and the contents of total P and soluble P were major factors influencing seedling growth. Alkali-decomposed nitrogen in the medium was the major factor influencing the ratio of the aboveground and underground parts of the seedling. The recommended medium prescription is surface garden soil: yellow earth: pine-forest surface soil: decomposed manure: coal cinder(=40∶15∶20∶20∶5) for Chinese Pine. The best medium is: the texture is neutral, apparent density is 10 t·m-3, total P is 0.8 g·kg-1, soluble P is 90 mg·kg-1, soluble K is 260 mg·kg-1,alkali-decomposed nitrogen is 112 mg·kg-1, organic matter content is 3.4%.
